    From what I've read in this forum, the nitrite spike will last longer than the ammonia spike - once the nitrites start staying at 0, you will see your nitrates go up more - are you cycling with fish? Asking because you have been doing water changes. It's my understanding that if you are cycling without fish, there is no need to change the water until you want your nitrates to go down in order to add fish in the end.

    You have grown enough ammonia eating bacteria with your current stock so are showing 0 ammonia. The nitrite eating bacteria is not guite yet matured enough so you still are seeing it. It will drop to 0 as well unless you start cleaning your filter or mess the cycle up in some way.

    Nitrites are as toxic as ammonia so do water changes to bring it down but don't do other cleaning. You may have to do a 50% water change today and again tomorrow. Two weeks is a short cycle with fish so I assume you haven't many in the tank? Add no more fish until you have 0/0 and less than 20 in nitrates.

    Yes, it is cycling properly altho a very, very small amount of bacteria has been grown with so few fish in so much water. You will probably have a bit of a spike after each addition of new fish. 5 Danios in nearly 80 gallons of water certainly couldn't have given you much bacteria at all.

    PS......what do you plan to stock in this tank? Also, what kind of test kit do you have? I'm not familiar with .05? Do you mean 0.50?

    I have a jbl master test kit that you have to take water samples and add reagents to the sample then match the color of the water to the chart. The nitrite chart have heasures from 0, 0.025, 0.05, 0.1 and so on untill you get to 1.0. As for fish i cant decide i did want cichlids but you have to have them on there own and dont want just one type of fish, so was thinking a male betta a ruby shark a nice size pleco is there any type of cichlid that i could put with those fish

    I"m still new at compatability but I am suspecting that a betta is probably not a good bet with some of the other fish due to its long fins and I also wonder whether the crabs are a good idea. Hopefully someone who has more experience with compatibility issues will chime in here before you get these fish.
